Weird head motion

I don’t have footage of it but, it seems like almost everyday mainly after she eats, she almost like gulps, then she does a almost gaping type motion close her mouth, and open it again, it almost looks like coughing but I’m not sure. She also closes her eyes during it, and imma add this last part in here but she also sometimes closes one eye but not the other, one last thing, she also seems kinda lethargic and lazy so idk just not sure what to do.
